南极气象监测对于全球气候变化研究具有重要意义,近年来各国对南极气象的监测愈发重视,在南极建立的自动气象站也越来越多,越来越深入内陆。自动气象站的工作环境存在着气候恶劣、长期无人值守等困难条件,因此对气象塔的结构强度和稳定性有着较高的要求。本文对气象塔的结构强度及其对风速测量的影响进行了研究。使用前期实测得的南极泰山站的较大风力日2017年7月17日24小时的气象数据进行流固耦合的分析,在计算尺度系数为20的情况下循环一个月最小安全系数仍有1.065,说明气象塔目前的结构有着良好的疲劳寿命,保证了气象塔在无人值守的情况下能长时间提供南极气象数据。通过对其屈曲稳定进行分析,得到其在50 m·s^(-1)的大风天气下最小安全系数仍有3.8016,说明了气象塔在南极大风天气下仍可以保持稳定。对气象塔在不同风速下的工作情况进行仿真模拟,得到其相对于原本风速的最大平均偏差仅为1.37%,说明了气象塔的结构对风速传感器的测量数据的影响小,保证了其监测得到的南极气象数据的可靠性。

The LIGO detection of gravitational waves(GW) from merging black holes in 2015 marked the beginning of a new era in observational astronomy. The detection of an electromagnetic signal from a GW source is the critical next step to explore in detail the physics involved. The Antarctic Survey Telescopes(AST3),located at Dome A, Antarctica, is uniquely situated for rapid response time-domain astronomy with its continuous night-time coverage during the austral winter. We report optical observations of the GW source(GW 170817) in the nearby galaxy NGC 4993 using AST3. The data show a rapidly fading transient at around 1 day after the GW trigger, with the i-band magnitude declining from 17:23 ± 0:13 magnitude to 17:72 ± 0:09 magnitude in ~1:8 h. The brightness and time evolution of the optical transient associated with GW 170817 are broadly consistent with the predictions of models involving merging binary neutron stars. We infer from our data that the merging process ejected about ~10^(-2) solar mass of radioactive material at a speed of up to 30% the speed of light.

为攻克冬奥会等顶级赛事高山滑雪项目赛道制作技术,在黑龙江省亚布力体育训练基地、张家口密苑云顶乐园和北京延庆国家高山滑雪中心开展了多次冰状雪赛道制作试验,发现-12℃晴空天气条件最适宜开展赛道制作,最优方案为-15~-10℃(气温)/6~9 bar(注水压力)/4~8 s(注水时长)。基于试验数据,建立了冰状雪赛道合格标准,以及国际上第一个冰状雪赛道制作的天气-注水定量模型,该模型可应用于大陆性气候条件下高山赛事并有潜力推广至其他冷干地区。此外,研究发现人造雪含水量和微观结构对赛道质量有显著影响,含水量越低、雪颗粒越小、雪形态越均一,赛道稳定性和硬度越大。研究成果弥补了国内有关冰雪体育保障技术的空白,可为我国承担大型冰雪赛事提供智力支撑。

Earthquake Research in China 2014年第4期28卷 491-501页

作者： Li Jin Jiang haikun Song Jin Gui Rong Ji Zhanbo wen Shaoyan Earthquake Administration of Xinjiang Uygur Autonomous Region China Earthquake Networks Center Kashi Standard Seismic Station Earthquake Administration of Xinjiang Uygur Autonomous Region Lanzhou Institute of Seismology China Earthquake Administration

A statistical analysis on earthquake activity in the Kashi-Wuqia intersection area triggered by earth tide is done by Schusters test and the Permutation test on daily and monthly scales. The north-south,east-west component of the tidal force and tidal body stress are chosen as the tidal curve in the daily scale. The results show that most of the earthquakes occurred near the maximum 0° of the three kinds of tidal curves,the predominant tidal phases of the earthquake are- 5. 86°,6. 60° and- 15. 52°,and the frequency of the earthquakes increases with the increase of the tide; with three kinds of tidal curves( the north-south,east-west component of the tidal force and tidal body stress),the p S of Schusters test for all the earthquakes is 10. 52%,2. 40% and 2. 06%,and the p P of the Permutation test is 10. 90%,2. 40% and 2. 06%,and the results of p S and p P based on the east-west component of the tidal force and tidal body stress are below the threshold of 0. 05 that tidal triggering of earthquakes. In the monthly scale,both the p S and p P are very low( close to 0),far below the threshold of 0. 05 of tidal triggering of earthquakes,and the predominant tidal phase for earthquake triggering is- 18. 95°,close to the maximum 0°( new moon and full moon) of the earth tide in monthly scale. Regarding the statistical test result of tidal triggering of earthquakes,a preliminary explanation is given as to why the trigger effect in the east-west direction is greater than that in north-south direction.

基于Schuster检验及Permutation检验方法,对喀什-乌恰交汇区地震活动受固体潮触发情况进行日尺度及月尺度检验。其中日尺度分别选取引潮力南北分量、东西分量及潮汐体应力作为潮汐曲线。研究结果显示,该地区地震活动均较多的发生于3种潮汐的最大值(相位0°)附近,优势发震相位分别为-5.86°、6.60°以及-15.52°,且发生地震的频次随潮汐力的增大而增加;利用3种潮汐曲线(引潮力日尺度南北分量、东西分量以及潮汐体应力)对所有地震进行Schuster检验所得pS值分别为10.52%、2.40%以及2.06%,Permutation检验所得pP值分别为10.90%、2.40%以及2.06%,其中基于引潮力东西分量及潮汐体应力的pS、pP值均低于潮汐触发地震的阈值0.05。月尺度Schuster检验pS值及Permutation检验pP值结果均非常小(接近于0),远低于潮汐触发地震阈值0.05,优势发震相位φ为-1.91°,较为接近月尺度下的固体潮最大值0°(即农历朔、望)。对潮汐触发地震的统计学检验结果即东西向潮汐触发效应大于南北向触发效应的原因进行了初步解释。

2013-06—07在广西平果铝3号排泥库附近发生小震群活动，震中空间分布集中，震源深度较浅。地震波形特征表明，有流体参与地震过程，较大地震震源机制的主压应力方向与区域构造应力场方向不一致。基于传染型余震序列模型（ETAS模型）的定量检测显示，此次震群流体触发强度较高，排泥库泥浆泄露对地震活动触发有直接影响。
